第7题：

A customer has no available floor space for expansion and room for only one disk enclosure pair in their DS8700. Four disk enclosure pairs are required to meet the current I/O needs of a data warehousing application. They are only utilizing 10% of their total capacity. Another application workload needs to be added to the system but requires two disk enclosure pairs. The customer is considering SSD and Easy Tier.  Which of the following is the primary function of Easy Tier（）

• A、reduce power consumption per unit of storage
• B、balance the total workload with other DAs
• C、automatically moves hot spots to the appropriate resource
• D、SANtiering permits more flexibility by adding additional data paths

第8题：

Which two statements regarding configuring high availabily in the Cisco UCS is correct?（）

• A、High availability is enabled during the configuration of either HSRP or VRRP from global configuration  mode
• B、High availability is configured during the initial setup of both Fabric interconnects
• C、High availability can only be configured via the CMC
• D、High availability is enabled during theinitial configuration of one of the Fabric  lnterconnects

第9题：

Which of the following is an advantage of hardware RAID over software RAID？（）

• A、Hardware RAID costs less than software RAID
• B、Hardware RAID is built into the operating system’s software
• C、Hardware RAID has better performance than software RAID
• D、Hardware RAID requires no configuration and software RAID does

第10题：

A company is deploying a Microsoft Windows-based， mission-critical Data Warehousing application.  The customer has specified 4GB of RAM.  Which TWO of the following questions will best help the consultant determine the proper memory configuration？（）

• A、Does the application require a large paging space？
